What is Low Molecular Weight Heparin Sodium?

Low-molecular-weight heparin sodium belongs to an anticoagulant drug, which mainly inhibits the formation of blood clots, including arterial and venous thrombosis as well as blood clots in vivo and in vitro. The anticoagulant effect of low-molecular-weight heparin sodium is generally exerted through anti-X factor. It can be used to treat deep venous thrombosis, myocardial infarction, and angina pectoris. However, the use of this drug may cause some allergic reactions, such as skin itching and rash.

The effects of low-molecular-weight heparin sodium include anticoagulation and antithrombotic actions, which are mainly suitable for hemodialysis or blood filtration to prevent blood coagulation in extracorporeal circulation and prevent the formation of blood clots. In addition, it can also be used for coronary heart disease, angina pectoris, especially in patients with acute myocardial infarction. It can also be used for patients with cerebrovascular diseases, as well as for long-term bedridden patients, with subcutaneous injection to prevent the formation of blood clots.

In clinical applications, low-molecular-weight heparin sodium is generally administered twice a day. During application, adverse reactions may occur, among which local bleeding is more common, followed by ecchymosis at the injection site. It may also cause allergic reactions, such as redness, itching, and rash on the local skin. In some cases, it may lead to thrombocytopenia and increased transaminase levels.

The injection position of low-molecular-weight heparin sodium generally chooses subcutaneous injection or intravenous administration. Among the choices for subcutaneous injection, the abdomen is the best injection position because it has a large injection area, more subcutaneous fat, relatively fewer capillaries, a constant subcutaneous temperature, rapid drug absorption, and is not affected by movement.
